[Commonly Used Textiles Manual] Printing Pads

Overview

The blanket that acts as a buffer during the printing process is formed by sandwiching the plain cloth or by laminating multiple layers of adhesive cloth. The basic function of the printing pad is to firmly adhere the flexo plate to the plate cylinder so that no slip occurs between them. This is one of the most important parts of the printing process that requires effective control, and it is also crucial for obtaining print quality. The printing pad prevents stacking, reduces plate wear, controls the web well, reduces web breaks and maintains a good overprint. Printed liner products require a smooth surface, good smoothness, elasticity and abrasion resistance, as well as a certain degree of hardness and solvent resistance. For a variety of printing machinery.

nature

The printing pad is made by rubber mixing, cloth coating, lamination, vulcanization and other processes. From multi-layered specialty fiber products and synthetic rubber compounds as raw materials, fiber products and rubber are combined in heat and chemical energy in precisely controlled processes during manufacturing operations. The textile products of the printing blanket are different in each layer, and synthetic fibers and natural fibers can be used.

Print pad thickness should be consistent. The stable and uniform thickness facilitates the control of dot gain and guarantees a good printing effect. Generally, the thickness of the pad used for narrow-width flexible printing is 0.3 mm. In plate making, the thickness of the liner is a major consideration.

classification

According to the hardness, printing pads can be divided into three categories: soft pads, neutral pads, rigid pads. In addition, printing pads can also be divided into printed pads and gravure pads.
